2. 27mm Kool using magnetic inductance ring, 1mm double-wound inductors, high-quality filter capacitor, enter a 1000uF63V electrolytic capacitor, the output of the two 470uF100V electrolytic capacitors, boost power output and better quality, on-board power supply switch, power indicator light, with voltage regulation, current adjustment potentiometer so that the output is more convenient, you can always adjust the output voltage, current size, using the 8500 input and output terminals, through a strong current capacity to ensure long and reliable operation.

Applications: 1. DIY an output adjustable vehicle power supply, only need to enter the access 12V supply, the output voltage can be (14V-80V) freedom continuously adjustable, but the output voltage can not be lower than the input voltage.

2. Universal car laptop power supply. 12V power input connected to the output regulation voltage into the notebook needs to work.

3. Boost charger, 12V power supply can be used for battery charging higher than 12V, such as 24V battery and charging current can be adjusted. 4. Electronic equipment supply, as long as the voltage is adjusted to the voltage required and current does not exceed the rated current can all be working properly. 5. System-level power supply before, when doing a project, the input of 10V-18V, 24V power supply system board around and need a lot of power, ordinary DC-DC module power is too small, then this module will be your best choice, without debugging directly on the machine can work easily achieve high efficiency power boost.
